Mini pipe bender

Small pipe bender is used for the formation of pipe bender, the main power is hydraulic cylinder or chain transmission, heating method is medium frequency heating

Pipe bender technology.Pipe bender is used to bend pipe as well as sheet material.In the case of pure bending, the pipe with outer diameter D and wall thickness t is bent under the action of external torque M, and the outer wall of the neutral layer is subjected to the action of tensile stress σ1, and the pipe wall becomes thin.Under the action of tensile stress σ1, the inner wall of the neutral layer becomes thicker.In addition, due to the action of the resultant force F1 and F2, the shape of the cross-section changes from a circle to an approximate ellipse. When the deformation is too large, the outer wall of the tube will crack, and the inner wall of the tube will wrinkle.The deformation degree of the pipe depends on the relative bending radius R/D and relative thickness T /D values. The smaller R/D and T /D values are, the greater the deformation degree is.In order to ensure the forming quality of pipe fittings, the deformation degree must be controlled within the permissible range. The bending forming limit of pipe not only depends on the mechanical properties of the material and the bending method, but also considers the application requirements of pipe fittings.In addition to pipe bender, our company also produces medium frequency elbow machine, tee machine, pipe expanding machine, beveling machine and other pipe fittings equipment and pipe fittings machinery which are very needed in the market.

Hydraulic medium frequency pipe bender

The principle of hydraulic medium frequency pipe bender is very simple;The medium frequency pipe bender is composed of cylinder, bracket and mould.The plunger on the main cylinder is connected with the mold, and both ends of the pipe are fixed on the bracket. The output of the cylinder in the middle bends the top of the pipe to a certain Angle.

Advantages are more: simple and easy to operate, the diameter of the elbow is larger.

Disadvantages: large diameter pipes cannot be formed in one go and are slower.Different size molds are required for pipes of different diameters.Medium frequency pipe bender can be divided into two kinds: hydraulic medium frequency pipe bender and chain medium frequency pipe bender

General hydraulic medium frequency pipe bender for 21mm-920mm, 1020mm-1620mm general selection of chain medium frequency pipe bender

Of course, and can be selected according to the specific requirements of customers.In addition to the production of medium frequency pipe bender, we also produce three-way machine, medium frequency pipe expanding machine, elbow machine, elbow pushing machine and other pipe fittings equipment and pipe fittings machinery.It is mainly sold to the United States, India, Malaysia, Singapore and other countries, and has won unanimous praise and repurchase from customers.
